Hover the Carbonite Button Window with your mouse. You
should see something similar to the box around the Carbonite minimap button (your colors will be different). Without the big red arrow, of course.
While hovering the button window, if you do not see a box around the Carbonite minimap button, this means the button window is locked. Please open Carbonites options to the "Map Minimap" page, and scroll down til you see the "Lock button window" option and
UNcheck it. Put your cursor in the box, hold the left mouse button and move the button window where you want it. Re-lock it and you're finished.
